Too little or too much sleep can cause short life
A new study finds that people who sleep too much or too little have a shorter life span than those who sleep eight hours a day.
Finnish researchers on 2.
10,000 adults conducted a follow-up study for 22 years, and found that during the study period, people who often sleep for 7 hours or more continuously are more likely to die.
The results of this study prove that sleep habits are related to physical and mental health.
However, the reasons why too much or too little sleep increases the risk of death have not yet been conclusive.
They believe that the reasons may be diverse, because people who have too much or too little sleep have their own special conditions, many of which are related to disease.
For example, less sleep time may be due to the relative need for sleep, or due to insomnia or other health problems.
Similarly, the long sleep time may be due to some potential diseases in the body.
Studies have found that men who sleep less than 7 hours are likely to die 26% more than men who sleep 7 to 8 hours, and women 21% more likely to die.
Men who sleep more than 8 hours are likely to die 24% more than men who sleep 7 to 8 hours, and women 17% more likely to die.
Researchers point out that although other studies have shown that sleep habits are related to poor health conditions, such as diabetes (and heart disease), the relationship between sleep and life is currently unclear.
